Patent EP-0540636-A1 (EP)
Inventor: WILLIAMS RICHARD GUY CARRINGTO
IPC: H04L27/34
Filed: 1991-07-26
Abstract: On génère un bloc de symboles de sortie à partir d'un bloc de bits d'entrée en utilisant la modulation d'amplitude en quadrature. Les bits d'entrée sont traités au moyen d'un ou plusieurs codes redondants possédant une distance de Hamming supérieure à un, pour produire des mots numériques qui commandent les composantes en phase ainsi que des mots numériques qui commandent les composantes en quadrature des symboles de sortie. Un groupe de bits généré par une simple étape de codage fournit des bits pour les deux types de mots numériques, permettant de ce fait à cette étape de codage de traiter simultanément un plus grand nombre de bits que ce ne serait le cas si on utilisait un codage séparé pour produire les deux types de mots.

Abstract: An attachment for a fork truck is in the form of a clamping device with two clamp arms (8, 9; 10, 11) or clamping jaws (12, 13) hydraulically movable towards and away from one another. It has in each case at least one flat, plate-shaped clamping element (14), or a plate-shaped clamping element (14) curved like a cylinder shell section, held on the clamp arms (8, 9; 10, 11) or clamping jaws (12, 13) and having a friction lining for bearing against the load. At least one clamping element (14) or each clamping element (14) held on the clamp arms or on the clamping jaw or jaws (12, 13) can be moved in the clamping direction up to a stop away from the arm or the clamping jaw and back and is also held with clearance of motion in a direction perpendicular to the clamping movement. The movably held clamping element or each movably held clamping element is connected to the clamp arm or the clamping jaw via an expanding device. The expanding device (17, 18) can be actuated by the respective force and motion component transmitted to the clamping element by the lifting load and running perpendicularly to the clamping direction. In the process, the expanding force changes linearly with the said force component. <IMAGE>

The capacitor is connected to a second reference-voltage source (when the ballast is switched off) and is charged using the first time constant, the comparator produces a switching signal on exceeding a lamp limiting voltage after the ballast has been switched on, the capacitor is connected to earth, via a resistor, by means of the switching signal and is charged using the second time constant. …<IMAGE>…

Abstract: Provision is made for a combination of flow-guiding devices to be designed in such a way that a partial propeller casing is arranged as a saddle nozzle above the propeller like the top part of a Kort nozzle and is stiffened owing to the fact that roughly horizontal or radial guiding surfaces situated in front of or behind the propeller statically form a unit with the saddle nozzle so that the rigidity of the saddle nozzle and the strength of the flow-guiding surfaces are increased. At the nozzle part of the system of flow-guiding surfaces, the distance from the tip circle of the propeller blades in the inlet and outlet area of the propeller blades is increased to reduce the vibrations which are caused by the thrust pulses circulating with the propeller-blade tips. <IMAGE>

Abstract: Un mécanisme servant à faciliter la conversion métrique d'images numérisées destinées à être utilisées dans un environnement à multirésolution et multiapplication, est incorporé dans les mécanismes de codage et de décodage de la base de données hiérarchisée de sorte que les fichiers d'images résiduelles stockées en mémoire contiennent des informations relatives à la conversion métrique. Dans un mode préférentiel d'exécution de l'invention, l'opération de conversion métrique est exécutée sur un fichier dont la résolution spatiale est relativement faible, ceci produisant une réduction sensible du temps système du traitement étant donné qu'on profite de la disponibilité de la taille réduite du fichier de base à faible résolution spatiale se trouvant dans la base de données hiérarchisée, de sorte qu'on peut effectuer la conversion métrique sur le nombre relativement faible de pixels situés dans le fhichier de base, avant de transformer l'image en l'agrandissant pour obtenir une image dont la résolution spatiale est relativement élevée, équivalant à 2048 X 3072 pixels par image pour commander une imprimante thermique numérique couleur à haute résolution.

Abstract: A rotary disc filtration device having a fluid filtration gap between a filtration surface and a disc is disclosed. The disc and/or filter has one or more spiral grooves in fluid communication with fluid in the gap. The disc and/or filter is rotated and one or both may be axially oscillated and/or vibrated to create the shear at the filter surface that increases permeate flux through the filter. Several discs and filters may be interleaved to increase filtration device capacity and make more efficient use of equipment space. In such a device, the discs can be mounted on a common shaft for rotation in unison and can have spiral grooves on both major faces of each disc. The filters are held stationary in that device and are fluidly connected to facilitate collection of the permeate.
